Yardscaping l.jpg
YardScaping

  • A new paradigm?

  • Some call it “Sustainable Landscaping” or “Ecological Landscaping”

  • We want to keep it simple


Yardscaping mission l.jpg
YardScaping Mission

  • To inspire Maine people to

    • create and maintain healthy landscapes

    • through ecologically based practices that

    • minimize reliance on water, fertilizer and pesticides




Bayscaping project l.jpg
BayScaping Project

  • Friends Of Casco Bay did some detective work in 2001, 2002, 2003, 2005 & 2006

  • Sampled runoff water from intensive lawn care areas in Cumberland, S Portland, Westbrook, Falmouth, Yarmouth, Brunswick, Freeport, Portland and Cape Elizabeth & Back Cove area

  • Sampled sediments for pyrethroids in 2006 – All samples were

    • “no detectable levels”


Friends of casco bay sampling l.jpg
Friends of Casco Bay Sampling

  • 2001 Sampling

    • Found Diazinon in 1 of 3 samples (2.6 ppb)**

    • Found 2,4-D in all 3 samples (36.4 ppb)

    • Found Dicamba in 1 of 3 samples (3.8 ppb)

    • Found MCPP in 2 of 3 samples (26 ppb)

    • Found Nitrogen & Phosphorous in all samples

  • 2002 Sampling

    • Found Diazinon in 4 of 11 samples (.71 ppb)

    • Found Nitrogen & Phosphorous in all samples

  • 2003 Sampling

    • Found Dicamba in 3 of 10 samples (4.1 ppb)

    • Found Clopyralid in 1 of 10 samples (0.91 ppb)

    • Found Propiconazole in 2 of 10 samples (0.075 ppb)

**Values in red exceed ALC


Back cove project l.jpg
Back Cove Project

  • 2005 Sampling

    • Found 2,4-D in 2 of 5 samples (4.62 ppb)

    • Found MCPA in 2 of 5 samples (0.45 ppb)


Aquatic life criteria l.jpg
Aquatic Life Criteria

  • EPA criteria for nuisance algae growth

    • Nitrogen - 250 ppb Phosphorous – 20 ppb

  • EPA just proposed diazinon level of 0.1 ppb for fresh water

  • Other criteria proposed by various sources for fresh water (from USGS Fact Sheet 097-99)

    • 2,4-D – 4 ppb Dicamba – 10 ppb

    • MCPA – 2.6 ppb Triclopyr – 560 ppb

    • Carbaryl – 0.02 ppb Chlorpyrifos – 0.001 ppb


Usgs national water quality assessment l.jpg
USGS National Water Quality Assessment

  • Sampled urban streams

    • Insecticides occurred more frequently in urban streams than they did in agricultural area streams

    • Herbicides detected in 99% of Urban stream samples

    • Phosphorous found at same levels as in agricultural streams

      • 70% of those samples exceeded the EPA level for causing excessive algal growth


The tenets of yardscaping l.jpg
The Tenets of YardScaping

  • Use site appropriate, non-invasive plants

  • Right plant, right place, right purpose

  • Use diversity of plants & grasses

  • Create wildlife habitats

  • Reduce lawn area

  • Use low input lawns & landscapes

  • Use vegetative buffers to protect surface waters

  • Reduce runoff

  • Reduce reliance on pesticides, fertilizers and water

  • Promote sensible pest management (IPM)


Use site appropriate non invasive plants l.jpg
Use site appropriate, non-invasive plants

  • Native plants are well adapted

    • Fewer problems, less work, more rewards

  • Invasive plants are easy to grow but crowd out native vegetation

    • Our local forest habitats are changing rapidly

    • Invasive plants ruin wildlife habitat


Right plant right place right purpose l.jpg
Right plant, right place, right purpose

  • Choose plants based on the area to be planted not just for their color

  • Select plants that thrive under existing conditions rather than trying to alter the conditions to meet the needs of a plant

  • Minimize disturbance of the existing landscape


Right plant right place l.jpg

Common Ninebark – dry sunny site

Right plant, right place

Cinnamon Fern – wet shady site

Staghorn Sumac – large open dry bank


Use a diversity of plants grasses l.jpg
Use a diversity of plants & grasses

  • Less noticeable damage from pests and disease

  • Incorporate many layers of plant types

    • Trees

    • Shrubs

    • Ground covers

    • Perennials, and

    • Lawns


Create wildlife habitats l.jpg
Create wildlife habitats

  • Diversity and plant layers go hand in hand with habitat creation

  • Add nectar and fruit producing plants

  • Strive for continuous blooms

  • Add water, walls, feeders, woody debris


Reduce lawn area l.jpg

Mower exhaust = 40 small cars’ exhaust

Reduce lawn area

  • Reduces

    • Water & air pollution

    • Water usage

    • Maintenance

    • Costs

  • Gives

    • More free time


Use low input plant varieties l.jpg
Use low input plant varieties

  • No-mow fescue vs Kentucky bluegrass

  • Pagoda dogwood vs flowering cherry

  • River birch vs paper birch


Protect lakes streams with buffers l.jpg
Protect lakes & streams with buffers

  • Preserve existing landscape

  • Winding paths

  • Don’t mow to lake’s edge

  • Pitch the rake


Reduce runoff l.jpg
Reduce runoff

  • Reduce amount of pervious (hard) surfaces

  • Create rain gardens or install rain barrels

  • Direct water into vegetated areas



Reduce reliance on pesticides fertilizers and water l.jpg
Reduce reliance on pesticides, fertilizers and water

  • Grow plants that are resistant to insects & diseases

  • Use plants that tolerate low fertility

  • Use drought resistant plants

White Fir

Sweet Fern


Use common sense pest management l.jpg
Use common sense pest management

  • Integrated pest management

    • Know your pest

    • Pick it, trap it or exclude it

    • Know the good bugs

    • Mow, prune or water

    • Use pesticides as last resort
